To all whom it may concern:

Be it known that I, BENJAMIN SKmMoRn,

Jr., a citizen of the United States, residing. at Chlcago, 111 the county of Cook and State of llllnols, have lnvented certain new-and useful Improvement in Condensers and specification. V

This invention relates toimprovements 1n condenser and vacuumpump and oneof the objects of the same is to provide an im- Vacuum Pumps, of whichthe following is a proved simple and efiicient apparatus of this" character, particularly adapted, though not necessarily limited in its use with a steam turbine and when so'employed maybe di- Igectly coupled to the shaft of the steam tur- To the attainment, of these ends and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty in substantially the construction, combination. and arrangement of theseveral parts hereinafter more fully described and claimed and ,shown in the accompanying drawing illustrating this in-.

vention and in which v Figure 1 is a vertical sectional view taken on line 1-1 Figure 2;

Figure 2 is a'vertical sectional view taken on line 2-2, Figure'l.

a modified form of the invention.

Referring more particularly to the drawing the numeral 10, designates a shaft which is rotated in any desired orsuitable manner. This shaft is journaled in suitable bearings 11, carried by asupporting base 12. Connected with the shaft 10, to rotate therewith is a rotor 13, which may be of any The casing 16,Iis of an internal diameter considerably larger than the external diameter of the rotor and interposed between the Figure 3 is a view similar to Figure 2 of .rotor and thewall of the oasingandspaced from each are aseries'of angularly disposed. stationary blades 19, having passagesfao .50 chamber or passage 21, l ietwee'nthe blades p i and the wall of the casing '16, anda lso a chamber or passage 22, disposedbetweenthe blades 19, and the "periphery of the rotor 4' I communication with each other throughflthei therebetween. These blades j 19,1 for'in fa 13, and which chambers or passages'have passages 20.

The casing 16, is. also provided'jwith an" inlet opening 23, forv the steam or vapdrto thereof, and within the blades 14.

If. des'iiedfsuitable packing such a;s;la'by-:' rinth rings 24, may be provided between; the rotor l3, an'd the wallfofthe to 1 form a fluid tight joint.

26, are arrang d around the shaftadjacent ofthe casing to form fluid tight joints:

In operation and when employedfas a condenser, the steam or vapor enters the iiilet; 28, andthe water or cooling enter the casingthrough the inlet 17..- The toolj ing fluid Ifills the. passage 21, and then flows through the passage ways'20, ibetweenthej blades 19, and into the passageway 22; i As theroter 13, operates, the bladesll lg,

will throw any liquid by centrifugal force '80 the points wherei itpasses through thewalls fromthe roto'r into the space p p s age' yayg 22, between the rotorv and thebl'ades 19,1[and' in so doing together with theefiectof then broken up and form a spray in thepassage stationary blades..19, the liquid '.will"}be*9 22, thereby forming or creatingfa -l argecon f densing area and entraining any air that" is delivered tot-he rotor,the liquid and air being "finally :di'scliarglod wlth cons'iderableQ 'forcej through the' discharge, passageway. 18.

hen the apparatus is" used as a yacuum pump solely, a1r' or ot'her gases enter the rotor through the, inlet passage, 23,,a1id' are' then entrained by he action of the blades.

'14, and fthe"stationary blades 19,, on the liquid, the liquid and entrained gases 'being then discharged throughfthe discharge'foutlet passage 18,;thereby causing a afrtial vacuum or suction 1n the'p'assag'eway 23.

The angula rly dispese'd blades 14, render it .POSsible to discl'iarge the 'liquid'ra'pidly I the rotor and the wall of the casing to form from the rotor with a minimum amount of shock, and by deflecting the extremities 15, of the blades 14, in the direction of rotation of the rotor, the deflected ends'of the blades operate to spray the liquid.

This apparatus may be connected with the return line of a steam heating system by connecting the line at the inlet opening 23, ofthe casing 16, and when so employed, it is particularly advantageous in that should there be any steam or vapor in the return line it will be immediately condensed by the apparatus,

' In Figure 3 there is shown a modified or double form of apparatus embodying a casing 27, having an inlet 28, and discharge outlets 29 -30. Within this casing are arranged two series of stationary blades -3132, the blades 31, being spaced to form passages '33, therebetween, the blades 32, form passages 34, therebetween.

These two series of blades 31-'32 are arranged within the casing, opposite each other and on opposite sides of the rotor. and the blades are respectively spaced from passages 35-36, between the blades and the wall of the casing and passages 3738,

between the respectiveseries of blades and the periphery of the rotor, the passages 37 communicating with the discharge outlet passage 30, and the passage 38, communicating with the discharge outlet passage 29.

Theoperation of this form of the invention is the same as that shown in Figure 2, with the exception that the liquid which enters the inlet 28, passes to opposite sides of the rotor and is delivered through the respective passages-3334 to the rotor and from the casing is delivered from the respective passages 37'38 through the respective discharge outlet passages 30-29.

While the preferred forms of the invention have been herein shown and described it is to be understood. that various changes may be .made in the'details of construction and in the combination and arrangement of the several parts, within the scope of the claims, without departing from the spirit of this invention. 7
